Street photographers rarely extend their practice to encompass garbage, but it's some of the most rewarding stuff to photograph when you're out with a camera. Trash is not quite random; even though it can be scattered here and there, it gathers in certain corners and nooks. Garbage, always existing in a state of decay, trails a story behind it into the past. The stillness of garbage means that you can stop and consider it, circle and tilt the camera, ensure its place in the frame.
People are much tougher to shoot. They're always in motion, and although their movements can be predicted, it's impossible to know exactly what will happen at the moment that the shutter is pressed. Their story extends backward and forward through time, which makes them harder to abstract into an image. But when they're running down the street at you in a YOLO shirt, you hope for the best.
